Because electromagnetic heating steam boiler system works for a long time, deposition in steam generator 4 is caused to have dirt, now
Cleaning model can be opened to implementing to clean in steam generator 4.During cleaning, 2L scale removers are first added into water inlet from dosing mouth 10
Pipe 5, open blowoff valve 7, control system control magnet coil the slack tank of steam generator 4 is heated to 200 DEG C, set inflow as
40L/min, intake pressure is that 0.8Mpa starts to intake from water inlet 15, and current are sprayed quickly through water inlet pipe 5 by atomizer 6
Go out, the cold mist of ejection is attached on the inwall of steam generator 4, now temperature is 200 DEG C in steam generator 4, due to heat
Swollen shrinkage principle, water smoke sweeps away the dirt on the inwall of steam generator 4, falls into dust collecting box 8, opens blowoff valve 7, by collection dirt
Dirt in case 8 is excluded.
Usually shutting down an off-position dust collecting box 8 of cleaning weekly：Only need to open blowoff valve 7, by dust collecting box 8
Blowoff valve 7 is turned off after dirt discharge.
The convection action of Electromagnetic Heating scale inhibition characteristic, spray souring and hot and cold water during due to work, dirt can be with
The decline autodeposition of cold water to bottom, and enters dust collecting box, it is therefore desirable to is periodically opened in blowoff valve discharge dust collecting box
Dirt.Blowoff valve 7 is opened shutting down off-position, completes, grasps by blowoff valve 7 is turned off after the dirt discharge in dust collecting box 8
Make simple and efficient.
Exemplary description is done to the present invention above, it should explanation, in the situation for the core for not departing from the present invention
Under, any simple deformation, modification or other skilled in the art can not spend the equivalent substitution of creative work equal
Fall into protection scope of the present invention.
